Abstract
The utility model relates to a shock absorbing base assembly for a cab, which consists of a locking ring assembly, a bracket support, two shock absorbing cushion blocks, a supporting pillar, an upper shock absorbing sheath, a lower shock absorbing sheath, an upper washer and a lower washer, wherein, the locking ring assembly is connected with the supporting pillar; the two shock absorbing cushion blocks are respectively connected with the left and right ends of the bracket support; the bracket support, the upper washer, the upper shock absorbing sheath, the lower shock absorbing sheath and the lower washer are sequentially and movably sleeved in the supporting pillar from top to bottom; a support ring is arranged at the bottom of the upper shock absorbing sheath; an annular groove is arranged between the upper shock absorbing sheath and the lower shock absorbing sheath; the supporting pillar at the lower part of the lower washer is connected with nuts; a supporting sheath is arranged between the interior walls of the upper shock absorbing sheath and the lower shock absorbing sheath and the exterior wall of the supporting pillar; the axial length of the supporting sheath is smaller than the sum of that of the upper shock absorbing sheath and the lower shock absorbing sheath. The shock absorbing base assembly has the advantage of long service life.
Description
Technical field
The utility model relates to a kind of operator's compartment shock absorption device, particularly a kind of operator's compartment damping base assembly.
Background technology
At present, prior art has a kind of operator's compartment damping base assembly of vehicle, as shown in Figure 1, it comprises lock ring assembly 1, carriage bearing 2, two damping cushion blocks 3, pillar stiffener 4, last shock-absorbing sleeve 11, following shock-absorbing sleeve 5, upper gasket 6 and lower gasket 7, lock ring assembly 1 is connected with pillar stiffener 4, two damping cushion blocks 3 are connected to the two ends, the left and right sides of carriage bearing 2, carriage bearing 2, upper gasket 6, last shock-absorbing sleeve 11, following shock-absorbing sleeve 5 and lower gasket 7 are socketed on the pillar stiffener 4 from top to bottom successively slidably, last shock-absorbing sleeve 11 bottoms are provided with support ring 12, be provided with annular groove 14 between last shock-absorbing sleeve 11 and the following shock-absorbing sleeve 5, be connected with nut 8 on the pillar stiffener 4 of lower gasket 7 bottoms.Though the operator's compartment damping base assembly of said structure has certain damping effect, but also there is a weak point in actual use in it: when vehicle ' is on relatively poor road surface, operator's compartment can produce than big bang, make the suffered pressure of operator's compartment damping base assembly increase greatly, and, because last shock-absorbing sleeve 11 and following shock-absorbing sleeve 5 directly are socketed on the pillar stiffener 4, therefore, very easily make operator's compartment damping base assembly stressed excessive and cause shock-absorbing sleeve 11 and following shock-absorbing sleeve 5 by supercompression and deformed damaged, thereby greatly reduce the service life of operator's compartment damping base assembly.
The utility model content
The technical problems to be solved in the utility model is that a kind of operator's compartment damping base assembly that can increase the service life is provided.
For solving the problems of the technologies described above, the utility model provides a kind of operator's compartment damping base assembly of following structure: it comprises the lock ring assembly, the carriage bearing, two damping cushion blocks, pillar stiffener, last shock-absorbing sleeve, following shock-absorbing sleeve, upper gasket and lower gasket, the lock ring assembly is connected with pillar stiffener, two damping cushion blocks are connected to the two ends, the left and right sides of carriage bearing, the carriage bearing, upper gasket, last shock-absorbing sleeve, following shock-absorbing sleeve and lower gasket are socketed on the pillar stiffener from top to bottom successively slidably, last shock-absorbing sleeve bottom is provided with support ring, be provided with annular groove between last shock-absorbing sleeve and the following shock-absorbing sleeve, be connected with nut on the pillar stiffener of lower gasket bottom, wherein, be provided with support sleeve between the inwall of last shock-absorbing sleeve and following shock-absorbing sleeve and the pillar stiffener outer wall, the axial length of support sleeve is less than the axial length sum of last shock-absorbing sleeve and following shock-absorbing sleeve.
After adopting said structure, compared with prior art, the utility model operator's compartment damping base assembly has the following advantages: when operator's compartment damping base assembly is stressed, though last shock-absorbing sleeve and following shock-absorbing sleeve still can pressurizeds and compress, but owing to be provided with support sleeve between their inwall and the pillar stiffener outer wall, and the axial length of support sleeve is less than the axial length sum of last shock-absorbing sleeve and following shock-absorbing sleeve, therefore, when last shock-absorbing sleeve and following shock-absorbing sleeve are compressed to a certain degree, in other words, promptly when the two ends of support sleeve contact with upper gasket and lower gasket, under the supporting role of support sleeve, last shock-absorbing sleeve and following shock-absorbing sleeve will can further not compressed, thereby avoided the utility model operator's compartment damping base assembly stressed when excessive, last shock-absorbing sleeve and following shock-absorbing sleeve can be because of stressed excessive causing by the supercompression deformed damaged, thereby can prolong the service life of the utility model operator's compartment damping base assembly greatly.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model operator's compartment damping base assembly is described in further detail.
As shown in Figure 2, in this specific embodiment, the utility model operator's compartment damping base assembly comprises lock ring assembly 1, carriage bearing 2, two damping cushion blocks 3, pillar stiffener 4, last shock-absorbing sleeve 11, following shock-absorbing sleeve 5, upper gasket 6 and lower gasket 7, lock ring assembly 1 is connected with pillar stiffener 4, two damping cushion blocks 3 are connected to the two ends, the left and right sides of carriage bearing 2, carriage bearing 2, upper gasket 6, last shock-absorbing sleeve 11, following shock-absorbing sleeve 5 and lower gasket 7 are socketed on the pillar stiffener 4 from top to bottom successively slidably, last shock-absorbing sleeve 11 bottoms are provided with support ring 12, be provided with annular groove 14 between last shock-absorbing sleeve 11 and the following shock-absorbing sleeve 5, annular groove 14 is connected with adapter plate (not shown) on being located at vehicle frame, with fixing the utility model operator's compartment damping base assembly, prevent its double swerve, be connected with the nut 8 that prevents that lower gasket 7 from dropping on the pillar stiffener 4 of lower gasket 7 bottoms, be connected with spring cotter 9 on the pillar stiffener 4 of nut 8 bottoms, the effect of spring cotter 9 is to prevent that nut 8 from dropping from pillar stiffener 4, be provided with support sleeve 10 between the inwall of last shock-absorbing sleeve 11 and following shock-absorbing sleeve 7 and pillar stiffener 4 outer walls, the axial length of support sleeve 10 is less than the axial length sum of last shock-absorbing sleeve 11 and following shock-absorbing sleeve 7.
